Salvation from small meteorites will.

Salvation from small meteorites will.American and Russian scientists and military are unable to prevent such incidents meteorites as in Chelyabinsk region on 15 February. U.S. lawmakers concerned about the situation, NASA realized that unless the U.S. drops like a meteor, it is not possible to avoid the devastating effects. NASA Administrator Charles Bolden made this statement during a hearing before the Committee on Science and Technology air. According to him, the major difficulties come from the space agency's ability to track celestial objects with a diameter of less than 140 m. Currently, according to Bolden, NASA can determine their location close to the Earth in 10% of cases. "The fall in small meteorites can lead to loss of many people and cause significant damage to infrastructure." In Chelyabinsk from the meteorite with a diameter of 17 meters injured more than 4,000 people, the shock wave damage to seven thousand buildings. Representatives of the Lower House of Congress reminded NASA that in 2030 the agency must be able to monitor up to 90 percent of small celestial bodies or their fragments. Bolden, however, in turn, said he doubted that the goal will be achieved with this budget. Bolden assured that huge crash in the next few years threatens Earth. "NASA considers highly unlikely the next few hundred years, the world to face global catastrophe similar to that which led to the extinction of the dinosaurs."
